'''Basic Trope''': The EvilOverlord has a tendency to wear concealing plate armor.
* '''Straight''': The [[EvilOverlord Dark Lord Diabolus]] wears a suit of jet-black armor with a [[BlackCloak black cape]] and [[SpikesOfVillainy spiked shoulder pauldrons]].
* '''Exaggerated''': The Dark Lord Diabolus also has a face-concealing helmet shaped like [[NothingButSkulls a grinning skull]], the [[ShouldersOfDoom pauldrons]] are bigger than the helmet (and are also shaped like skulls), and the entire suit of armor has so many spikes that people wonder how he's able to move around in it.
* '''Downplayed''': The Dark Lord Diabolus goes into battle in realistic plate armor that is painted jet-black and possesses morbid heraldry.
* '''Justified''':
** The Dark Lord conceals his face either because TheDarkSide [[EvilMakesYouUgly has made it monstrously ugly]], or because he doesn't want to be recognized, or because he's in fact, a [[SamusIsAGirl girl]].
** The armor is for the protection and intimidation factor.
** Or it's a PoweredArmor.
** Or it's [[AnimatedArmor empty]].
** Or he's a {{robot|icReveal}}.
** Or [[ChromeChampion it's his skin]].
** Or he is very paranoid.
** Or it's [[DarkLordOnLifeSupport all that's keeping him alive.]]
* '''Inverted''':
** The hero is a BlackKnight who walks the earth in concealing plate armor to avoid being recognized by the Dark Lord's goons.
** The hero is a TerrorHero who uses the intimidating appearance of his armor to avoid unnecessary fights.
** The villain wears [[{{Stripperiffic}} a skimpy loincloth.]]
** The villain [[LightIsNotGood looks like]] a classic KnightInShiningArmor.
* '''Subverted''':
** The heroes finally bring down the Dark Lord in the black spiky armor... only to discover that [[ElCidPloy it was a body double]] used to make the populace believe the Dark Lord himself was leading the evil army.
** Dark Lord Diabolus does a HeelFaceTurn, and keeps the spiky intimidating armor.
* '''Double Subverted''': The real Dark Lord's armor is even more ornate, and decorated with spikes and skulls.
* '''Parodied''': The Dark Lord Diabolus never takes off his helmet or armor, even when he's in the shower.
* '''Zig Zagged''': Diabolus only wears the armor on special occasions.
* '''Averted''': The Dark Lord Diabolus prefers a fashionable BlackCloak to all that bulky armor.
* '''Enforced''': The author was a fan of Sauron in ''Film/TheLordOfTheRings'' movie.
* '''Lampshaded''': "Diabolus is wearing a gigantic suit of armor. Gee, no surprises here."
* '''Invoked''': Diabolus dresses as a TinTyrant so that his side can recognize him upon the battlefield.
* '''Exploited''': Diabolus wearing a ton or more of armor everywhere has made him extremely fit. While it's on, his only weakness is [[MightyGlacier being incredibly slow.]] When he [[ShedArmorGainSpeed ditches it]], he's got the benefit of [[CharlesAtlasSuperpower constant exercise from wearing a scrapyard all the time]] and is no longer weighed down by it.
* '''Defied''': "I'm not wearing that! Don't you realize how hot a suit of black armor gets in the summertime? It's like an oven in there!"
* '''Discussed''': "What is it with overlords and armor fetishes? Are the two related or what?"
* '''Conversed''': ???
* '''Deconstructed''':
** The Dark Lord Diabolus is really paranoid about someone trying to harm him, so he has heavily fortified armor look fearsome to protect himself while intimidating everyone from attacking him. Alternatively he could be making up for something.
** The Dark Lord Diabolus, while imposing, can barely move and is easily defeated.
* '''Reconstructed''':
** The Dark Lord Diabolus wears his deliberately over-spiked, oversized, and under-flexible armor all the time in order to [[{{PowerLimiter}} limit his own power.]] Anyone thinking that the armor-wearing is based around paranoia and weakness is in for [[{{FlyingBrick}} a nasty]] [[{{LightningBruiser}} surprise…]]
** The Dark Lord Diabolus's armor is far lighter then it looks, and he can still fight in it.
** [[PowersDoTheFighting Diabolus doesn't NEED to move to kill you.]] His primary combat strategy is [[TheSlowWalk a leisurely walk towards his goal]] [[TheJuggernaut while his opponents kill themselves on his powers.]]
** Diabolus can't move in his armor, but uses magic or technology to make the armor itself capable of moving while he wears it.
* '''Played For Laughs''': Diabolus ends up plummeting through the floor due to the weight of his bulky armor.
* '''Played For Drama''': The ScaryImpracticalArmour is in fact Scary, and Diabolus is TheDreaded largely due to the armor's fearsome reputation.
Back to TinTyrant. Don't forget to [[{{VillainousFashionSense}} dress properly]] first, though.
